[Solved] Dell Optiplex GX620 upgrades

The powersurply needs to be replaced. You will need a powersurply that is either a pce-e 2x6pin or 2x8 pin and atleast 500 wats to acturally power up the video card. If you try to use the powersurply that is included in the setup from dell you risk of damageing the hardware and causeing problems in the future.

According to Dell's specs the Mini Tower will provide 75 watts to the x16 slot. All other chassis formats provide 25 watts only. If you're really worried try a Radeon 5570 which is essentially a 40nm version of the 4670 with similar performance but less power draw.

and also to you knuckleheads -
the HD4670 or even the HD5670 doesn't require ANY power plugs adapters, just install card in proper slot and boot unit.

^
that will not even happen, if the power supply goes it will go because of TIME and not the HD4670..

DUDE.
DID YOU NOT READ WHAT I SAID.?!
WTF.?!

your psu is AXT standard psu so any aftermarket ATX supply will work.

Dear Malmental and 1965Ohio, WOW! Thank you all so much. That is great news! I was about to order a new PSU or return the 4670 card. If you truly think my Optiplex can handle the card with my existing power supply, then I'm good to go.
But Mr. Malmental, everyone else says i need a new PSU. Are you really running all that hardware off a 305 watt PSU? It sounds too good to be true when everyone else says i NEED the upgrade. But I do believe you, and I'm going ahead and I am going to install the new card into my PCI x16 slot unless I hear otherwise. Thank you all!

I will have to agree with malmental on this. The only reason to get a new PSU is if it dies for some reason. The video card top limit is only about 59 watts. Even if your CPU is 95W, the board and drives are only looking to add another 35 watts to it. So say 60+100+40... that's like 200. And this is all over estimates. Also, most Dell power supplies list the continuous, not the max. They usually are underrated.

I'll be waiting for the good results..
enjoy your upgrade..

It'll work. Don't worry. And even if your PSU was seriously stressed, the worst that will happen in a dead PSU, everything else will be fine. The only indication of a stressed CPU is if your computer bluescreens randomly or put your hand around the PSU and see if it has hot air coming off. Under load it will be a little warm anyways. You won't fry your motherboard or cause a portable nuclear core meltdown. Worst case is that you need a new PSU. So you are right back where you started when you started this thread. LOL!

Well, I'm back and I successfully installed the new graphics card. One thing I need help with though...all of my desktop program icons are huge and web page screen fonts are huge. I can't see all my programs in my Start Button or see whats all on a web page. Can someone help me shrink to fit my fonts and stuff, please.

Oh, okay. A quick restart set everything straight. Thank you all for your help throughout this graphics card installation. I couldn't have done it without all of your guidance. Thanks again. Now, what can I do with this GPU...find an online shooter game and go nuts or what?
PS If you guys at Toms wish to call this thread resolved you may. I am one satisfied newborn PC-gearhead. Thanks for everybody's help. Now, as they say in my country: It's Miller Time.

depending on what the rest of the specs are you can do some damage gaming...
I do not know the exacts of the HD4670 limits but it performs just slight of my 9800GT so I imagine it can do decent on medium settings..

Someone might have to walk me through any end-thread procedures here, I'm new to this stuff. But if I need to fill out a survey that indicates your massive helpfulness I will.
I will be checking my unit often for extra heat, I have experienced no blue screen activity. And you saved me the costs of a new power supply unit too. This Dell Optiplex GX620 has been good to me, and this Sapphire Radeon HD 4670 1GB GPU was as easy as "plug and play" to install. I am a happy camper.

Why just yesterday my PC had to pause while the Black-Ops game web page transferred information and loaded data to stream its content...with this new Radeon 4760 GPU the web page just instantly loads and runs its course. I am very pleased so far. As I assume this new boost in speed is accountable to the card itself. Is this the case?

Well, thanks again Malmental, So tell me this...will this new graphics card help me stream live television news broadcasts and such or is the GPU more just a gaming graphics accelerator? I use my Dell PC to stream local news in the mornings with coffee before work and some times the data transfer and page load-up is slow or simply stops; will this GPU help in that area too? If not, what recommendations do you have to remedy this? -I already use the 4GB maximum of RAM memory-

My PC's motherboard has four ram memory slots which hold four 1GB memory sticks, so I have 4GB ram memory total. Which I'm told is all this Dell Optiplex GX620 can run. -according to the Dell manual and Crucial.com- I bought the RAM memory in kits. -two 2x1GB kits-
Tell me something about these TV tuner cards, what the heck are they? They sound cool as...they sound cool. What are they? Why do I want one? Which one do I want for my PC?

Oh, okay. I understand. I wish I knew that before I bought four 1 GB sticks. I'll look into two 2GB sticks and run them in the proper dual channels on my motherboard as soon as possible. Excellent tip Malmental, I had no clue.

I have an old big screen tv. I want to use my tv as my computer monitor. Is this possible with my old tv? Its a GE VideoPlus GemStar. The tv has one yellow video input, two sets of red and white audio-in & audio-out inputs, one S-video port. and one coaxial cable port.
With this criteria, can you aid me in finding the correct wires and adapters necessary to connect my Dell PC to my regular TV? Thanks.

Dear Mr. Malmental, I started a new thread.

The thread is titled: How to use my TV as my computer monitor.

I hope you can assist me with this new project with easy wiring or simple modifications. Thank you for all of your help.

you could try a DVI to HDMI adapter

what are the exact specs of the RAM in question.?

The CL is 5 and the timing 5-5-5-15, 1.8 V

Yes, thats the one.
The stock Ram was PC2-4200, 533hz 1.8V with 5-4-4-12 timing and the bus clock speed is 266.67.
The new Ram is PC2-5300, 667hz 1.8V with 5-5-5-15 timing and not sure about the bus speed.
